This application is related to U.S. Provisional patent application Ser. No. 62/849,498, filed May 17, 2019 entitled “Electronic Gaming Machine and Methods for Playing a Hold and Drop Keno Game”, and U.S. patent application Ser. No. 16/870,550, filed May 8, 2020 and entitled “Electronic Gaming Machine and Methods for Playing a Hold and Drop Keno Game”, the disclosures of which are hereby incorporated by reference in their entirety.

FIG. 1 is a front view of a display screen or portion thereof with a transitional graphical user interface set showing a first image in a sequence according to our new design;

FIG. 2 is a front view thereof showing a second image in the sequence;

FIG. 3 is a front view thereof showing a third image in the sequence;

FIG. 4 is a front view thereof showing a fourth image in the sequence;

FIG. 5 is a front view thereof showing a fifth image in the sequence;

FIG. 6 is a front view thereof showing a sixth image in the sequence;

FIG. 7 is a front view thereof showing a seventh image in the sequence;

FIG. 8 is a front view thereof showing an eighth image in the sequence;

FIG. 9 is a front view thereof showing a ninth image in the sequence;

FIG. 10 is a front view thereof showing a tenth image in the sequence; and,

FIG. 11 is a front view thereof showing an eleventh image in the sequence.

The outermost dash-dash-dot broken line in the Figures illustrates a display screen or portion thereof and forms no part of the claimed design. The bracket shown in FIGS. 1-11 indicates a set, and forms no part of the claimed design. The graphical user interfaces of the sets are arranged relatively on the drawing sheets for the convenience of illustration, and the placement of each graphical user interface relative to another, or to the drawing sheet, forms no part of the claimed design. The appearance of the transitional image sequentially transitions between the images shown in FIGS. 1-11 . The process or period in which one image transitions to another image forms no part of the claimed design. Stippling in the drawings is used to indicate a contrast in appearance, with no specific color or other feature being claimed. The remaining broken lines represent elements of the display screen or portion thereof with a graphical user interface that form no part of the claimed design. 

CLAIM We claim the ornamental design for a display screen or portion thereof with a transitional graphical user interface set, as shown and described.
